摘要：

Solid-liquid equilibrium data of the n-alkanes from n-hexane to n-hexatriacontane dissolved in various alkane solvents have been used to determine the activity coefficients at infinite dilution. Comparison of the data obtained with vapour-liquid equilibriums, GLC and heat of mixing data suggests that almost ideal solubility in some systems results from an order/disorder phenomenon known as the Patterson effect. The importance of the combinatorial entropy contribution for the solubility of hydrocarbons has been discussed.
